IM PROVE M ENT IN PLOWS.

Specification forming part of Letters Patent No- 197,660, dated November27, 1877; application filed February 24, 1876.

To all whom it may concern:

Be it known that I, ALVY Gr. PERRY, of Hickory Flat, State ofMississippi, have invented certain Improvements in Plows, of which thefollowing is a specification:

This invention relates to certain improvements in plows; its objectbeing to provide a simple and eifective means for securing the plowshareto its standard, to adapt the plow for turning either right or leftfurrows, and to provide for conveniently adjusting the plow with respectto the surface being plowed, in order to regulate the depth of thefurrow at will and it consists in the combination,.with the plowshareand the supporting-standard, of a detachable and interchangeablemoldboard, which may be adjusted to turn the fur row either to the rightor left, as may be desired. I

In the drawings, Figure 1 is a perspective view, and Fig. 2 a sectionalview, of the standard and plowshare; and Fig. 3 is an end view.

tal oblique plate, B, to which the vertical standards G O are attached.D represents the plowshares, each of which is constructed of ashovel-shaped point provided with an aperture, d, to fit over the lugs0, formed on the lower ends of the standards 0 G for the purpose ofsupporting the plowshares, said shares being each held in place uponsaid lugs by means of a single bolt, E, passing through the standards.

To each standard, above the shovel-shape point, and resting against itsupper edge, is secured a curved mold-board or wing, so constructed thatit can be detached and another substituted for it, to turn the furrowsto the right or left, as may be desired. Said moldboard is secured tothe standard by means of a single bolt, G, and is prevented fromshifting thereon by the upper edge of the shovel-shaped point, againstwhich it rests.

The letter H represents a bent frame, carrying at its lower end asupporting-wheel, I. Said frame is enlarged at its upper end, and

pivoted to the rear of the plow-beam, the enlarged portions beingprovide dwith curvilinear slots i, through which the bolts K are securedin the plow-beam, said bolts being provided with screw-nuts, by means ofwhich the I frame may be clamped in any desired position in order toadjust the height of the plow with respect to the ground to be plowed,and thus regulate the depth of the furrow.

The operation of my improved plow will be apparent from the abovewithout further description.

The manner of using the improved plow is as follows: When it is desiredto convert the plow into a double-shovel plow, all thatis necessary isto remove the right-hand turningwings or mold-boards, and substitute intheir place a shovel-shaped top mold-board, which is raised in itscenter and set back on both sides alike. They fit the same plow sharesor points, which remain a fixture on the plowstandard. The letter Arepresents the plow-beam, to I the under side of which is secured ahorizon- When it is necessary to turn a furrow to the left, I substitutefor the right-hand turningwings similar, but left-hand, turningmoldboards or wings.

By the manner of attaching the plow share or point D, by means of asingle bolt and the lug c, the said point or share is independent of themold-boards or wings, and can be used without the use of the latter,which is often desirable in the cultivation of small corn.

What I claim, and desire to secure by Letters Patent, is

In combination with the plowshares and the standards, the detachable andinterchangeable mold-boards, whereby the plow is adapted to turn rightor left furrows, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this1st day of February, 1876.

ALVY GREEN PERRY.
